Many years ago, amanda was a once a day design, but about 15 years back
it was optionally made aware of time of day. From man amanda.conf, it
now says:
usetimestamps bool
Default: Yes. Deprecated, the value is always Yes. This option
allows Amanda to track multiple runs per calendar day.
Its # commented out in my config, has been for decades.
There is one option that can make amrestore in the event of restoring to
a new drive in case the old one failed, as if its set, it checks the
device and will not restore to a different replaement drive. I disabled
that check years ago because drives do fail.
See your amanda.conf under
define application-tool app_amgtar {
where there are a number of properties defined:
property "CHECK-DEVICE" "no" #use '--no-check-device' if set to "no"
This one can bite you if set to yes.
